“…In specific driving scenarios, the EM with the characteristics of start frequently, load disturbance changes rapidly and inaccurate model, which is a great test for the driving performance of the machine system. Permanent Magnet Synchronous Motor(PMSM) occupies the mainstream position in the EM machines [6,7,8]. PMSM stands out for its numerous distinctive advantages such as low energy consumption, dependable operation, and uncomplicated structure.…”

The Electric Mopeds (EM) drive system has the characteristics of frequent startup, rapid change of load disturbance and difficulty of establishing accurate mathematical model, this study proposes a modelfree double Fractional-Order integral sliding mode control (DFOISMC). Firstly, a new double Fractional-Order integral sliding mode surface is proposed to enhance the robustness and improve the dynamic response, and to improve flexibility of the conventional integral sliding mode controller (ISMC). Secondly, a super-twisting structure is chosen to suppress chattering phenomenon. Then, the model-free DFOISMC is constructed by utilizing the double Fractional-Order integral sliding mode surface, the super-twisting approach law and the ultra-local dynamic model of EM drive system. Furthermore, the stability of the closed-loop control system under the model-free DFOISMC is proved by the Lyapunov stability theorem. Finally, the digital simulation results demonstrate that the proposed control strategy is highly effective and superior.
